SOURCE INSPECTION EVALUATION: With the exception of sources that only monitor for opacity, quarterly report memoranda will only address the findings of the quarterly report. Approval Order and Title V permit conditions addressing continuous emission monitoring requirements will be addressed in Currant Creek’s relative accuracy performance specification test review memorandum.

CURRENT RECOMMENDATIONS: This report was submitted late on November 20, 2024, with a revised report being submitted on November 25, 2024, to fix errors noted in the first rendition. The report was due by October 30, 2024. A warning letter should be sent for the late SEDR. All other deviations appear to be a result of breakdown or process related problems that do not warrant issuing a violation. Periods of excess emissions that were recorded by the CMS in service on each point source during this reporting period are summarized in the SEDR and described in Pivot Table 400 “Excess Emissions Review.” Currant Creek was in compliance during this reporting period. No further enforcement action is recommended. Currant Creek’s NSPS monitoring system meets the performance standards of 40 CFR 60, Appendix B Performance Specifications. Currant Creek’s acid rain monitoring system meets the performance standards of 40 CFR 75 Acid Rain Performance Specifications. HPV: No RECOMMENDATION FOR NEXT INSPECTION: Check DAS for daily zero and span drift. Check the QC program to ensure that monitor drift is being tracked and that the source can identify excessive drift.
